The non-profit group that oversees international coding standards for smiley faces and other mobile characters is working on a range of skin-tones — including the existing yellow and five other shades.

The Unicode Consortium on Tuesday submitted a proposal for improving the uniformity of emoticons, which included suggestions for making emojis more diverse.

“People all over the world want to have emoji that reflect more human diversity, especially for skin tone,” read the proposal on the consortium’s Web site.

The working draft of Unicode Version 8.0, which is due next year, draws on the Fitzpatrick dermatology scale for six tones.

Activists have been calling for black and other non-white characters. The standard emoji face, used to represent the users’ mood in text messages, is actually yellow in color with a round face and no hair.

While there’s more diversity coming, the group doesn’t believe the code can — or should try — to represent all aspects of one’s appearance.

It’s “beyond the scope of Unicode” to represent diversity in other ways, such as “hair styles and color, use of eyeglasses, various kinds of facial hair, different body shapes, different headwear, and so on.”

It also suggested steering clear of gender-specific characters. With few exceptions, such as Father Christmas, “all others should be depicted in a gender-neutral way.”
